What is the temperature in space when an astronaut spacewalks?
Spacewalking astronauts face radiation, dust, debris, and extreme temperatures. Temperatures on spacewalks may vary from as cold as minus 250 degrees Fahrenheit to as hot as 250 degrees in the sunlight. The suits provide the proper pressure for the body and supply astronauts with water to drink and oxygen to breathe. Oct 4, 2019
